ELECTRIC RANGES

4322453

WHIRLPOOL CORPORATION assumes no responsibility for

any repair made on our products by anyone other than qualified

TECH-CARE®Service Technicians.

Electrical Shock Hazard

Disconnect the range’s line cord plug from the wall receptacle before you service

any of the components inside the unit. Failure to do this could result in violent

electrical shock.

VOLTAGE CHECKS

When making voltage checks, be sure to observe the following precautions:

1. The floor must be dry. Water and dampness increase the chances of electrical

shock.

2. Set the voltmeter correctly for the voltage being measured.

3. Touch only the insulated parts of the meter probes.

4. Touch the component terminals, or wires, with the meter probe tips only.

5. Touch the meter probe tips only on the terminals being checked. Touching other

components could damage good parts.

PARTS QUALITY

An important step in the appliance repair procedure is the selection of FSP®

(FACTORY SPECIFICATION PARTS) as replacements. Use of “fits-all,” or “look

alike” parts could result in early parts failure, safety hazard, or substandard perfor-

mance of a WHIRLPOOL appliance. It could also result in an unnecessary repeat of

your repair efforts.

To be sure that the part(s) you purchase meet the exacting quality standards used to

build every new WHIRLPOOL appliance, be sure to ask for genuine FSP replacement

parts, as specified for your model. “FSP” is a registered trademark of WHIRLPOOL

CORPORATION.

You can buy your genuine FSP replacement parts from any authorized WHIRLPOOL

Parts Distributor.
